A case is reported of a young girl who presented with macrodactyly of the right middle finger and tumour masses on the palmar side of both interphalangeal joints. The lesions were fibrocartilaginous and appeared to be hyperplastic palmar plates. The macrodactyly and the hyperplasia of the palmar plates were attributed to trauma.
1. A case of adamantinoma of the tibia was followed radiographically for seventeen years before a biopsy was performed. During this time there was an increase in size of the tumour and a gradual transformation of radio-opaque into polycystic areas. 2. Biopsy revealed a peculiar osteoid-like differentiation of the epithelial tissue.
